Description

 The invention relates to an aerosol spray device for controlling harmful insects capable of spraying large quantities of aerosol.

 The aerosol spraying device is a means for repeatedly spraying an aerosol that is closed inside the container in order to control harmful insects.

 It is desirable that everyone can easily use the aerosol spray device, and that the aerosol closed in the container is effective for controlling harmful insects and at the same time is a safe composition.

 A general view of the aerosol spray device 10 is shown in FIG. 1. In FIG. 1 under number 1 shows an aerosol container; at number 2 - a cap with a trigger; 31 - trigger; 34 - trigger; 37 - spray head. Number 7 shows a seal that prevents unauthorized triggering of the trigger during storage or transportation.

 In FIG. 6 is a side sectional view of cap 2, and in FIG. 7 shows a bottom view of the cap 2. At number 3 shows the trigger, which is inserted into the valve stem 6, protruding above the upper part of the container 1, this trigger is designed to actuate the valve stem 6; 31 - trigger; 32 - a fixing plate; 33 - locking lever; 34 - trigger. At number 35, an element for mounting on the valve stem is depicted (this element will hereinafter be called the seat for the stem); 36 - channel for the passage of fluid through the trigger 3; 37 — spray head at the end of a fluid channel; 38 - spray nozzle inserted into the spray head.

 Number 4 shows the housing mounted on the support 5 of the container 1; 41 - stiffener of the locking lever 33; 42 - reference limiter; 43 - circumferential wall in the cap; 44 - hole in the lower part of the circumferential wall.

 In a conventional aerosol spray cap, the aperture 44 is too narrow to fit the cap removal device 2, so it was difficult to remove the cap 2.

 As mentioned above, a seal is attached to the cap in such a way as to prevent the trigger from tripping by mistake during storage or transportation. That is, the seal completely blocks the spray until the operator begins to use the aerosol spray device.

 However, when the seal is attached to a different type of aerosol cap, which cap is shown in FIG. 9 and 10, the problems described below may occur.

 In FIG. 9 and 10 show an aerosol cap 105 in which there is a seal 102 in the upper part 101 of the trigger 107 having a trigger 100 and a spray head. The seal 102 is connected to the edges of the side wall 104 of the housing 103. If the seal 102 is removed with excessive force, then the trigger 107 may rise and the seat for the stem 109 will pop out of the rod 110. Since between the rear wall 106 of the housing 103 and the curved portion 108 of the trigger 107, a bending space S1 is formed, when the seal 102 is removed, for example, with the index finger, while the thumb is on the end of the trigger 107, sometimes situations arise where the trigger 107 rises backward, which leads t to severely bend the bent portion 108. After that, the stem seat for the stem 109 can pop out and stand on the valve stem 110, as shown in FIG. 11. In this case, the valve stem 110 is pushed down and the contents are jetted. In addition to these conventional spray valve systems, in which the valve stem is pushed down to spray, the so-called tilted valve systems, in which the valve stem is tilted so that the contents are sprayed, also situations arise where the stem mounting socket exits its place and contents are splattered by mistake.

 As for the aerosol in the container, various studies have been conducted to increase its effectiveness. For example, it was proposed to use a component for controlling insect pests having a potential insecticidal effect as an active ingredient, a composition of a stock solution containing a component for controlling harmful insects was studied, and a correction of spray intensity was proposed.

 For example, to control harmful insects, those aerosol preparations intended for use in an aerosol spray device that can be sprayed so as to apply high doses of the component for controlling harmful insects are effective (in the text of this application, such preparations will be referred to as “intensive spray” preparations ); studied several options for such drugs.

JP-B-46-20837 (in the text of this application, the term "JP-B" means "Examined Published Japanese Patent Application") describes an insecticidal spray material comprising not more than 10% (w / v) solution of the insecticidal component in a solvent having a boiling point of not higher than 100 ^o C and a melting point of not higher than 0 ^o C, and not less than 90% (v / v) of the aerosol propellant, which is sprayed through a special valve that can spray at an internal pressure of 3 to 7 kg / cm ^{2/20 o} C with a flow rate of 15 ml or more in secular In order to release the insecticidal component into a vast space in a short period of time (about 20 seconds for spraying 300 ml). However, this method is not suitable for widespread use, since a special valve requires an increase in production costs and cannot be sprayed repeatedly, since all the contents are sprayed at a time.

 Also described is an aerosol composition for intensive spraying containing a basic solution on kerosene and a propellant containing chlorofluorocarbon, explosive liquefied gas and carbon dioxide. This method sets the main task to reduce the content of chlorofluorocarbons (freons) in the propellant.

 The above conventional methods have several disadvantages arising from the fact that the contents are sprayed in excess in order to increase the effectiveness of insect control. That is, an excess amount of the sprayed material moisturizes the surface, and as a result spots and sticky spots form on the floor or on the walls. There is also a safety problem associated with the increase in the length of the torch. If the spraying intensity is reduced to avoid wetting the treated surface or increasing the length of the torch, then the control of insects will not be effective enough.

 Thus, conventional aerosol spray devices, especially intensive spray devices, have various disadvantages that need to be addressed.

 An object of the present invention is to provide an aerosol spraying device that overcomes the aforementioned disadvantages of the known devices and provides high-intensity spraying of the contents, while providing easy removal of the cap from the container.

 This technical problem is solved due to the fact that the aerosol spray device comprising a container for airtight aerosol containing a solution comprising at least a component for controlling harmful insects and a propellant, a valve stem protruding above the top of the container, and a trigger that is mounted on the valve stem and has a channel connecting the valve stem to the outer space, the aerosol from the container being sprayed into the outer space by means of a trigger, an aerosol a cap formed by a cap mounted on a support at the top of said container and a trigger, the trigger having a spray head at the outer end of its channel, a trigger whose one end is in close proximity to the spray head and is mounted at the other end a locking plate, and a locking lever formed on an end portion of the locking plate that is held in the support stop on the locking plate, while the locking lever is held in According to the invention, the stopper at the lower end of the stiffening rib, made on the rear end side of the cover, further includes an opening at the lower end of the circumferential wall of the cover and below the locking lever, which is wide enough for the tool to be inserted and operated to remove the cover.

 In this case, preferably the aerosol contains an amount of propellant at least two times the amount of the solution comprising at least a component for controlling harmful insects, and the spraying intensity of the aerosol is at least 5 g in 5 seconds.

 In addition, preferably the aerosol contains an amount of propellant in excess of 2-7 times the amount of a solution comprising at least a component for controlling harmful insects.

 Preferably, the aerosol contains an amount of propellant in excess of 3-5 times the amount of a solution comprising at least a component for controlling harmful insects and a solvent, the amount of sprayed solvent being at least 4.0 ml per 10 seconds.

 In addition, the technical problem is solved due to the fact that the aerosol spray device, comprising a container for the hermetically sealed aerosol placement, consisting of a solution comprising at least a component for controlling harmful insects, and a propellant, a valve stem protruding above the top of the container and the trigger, through which the aerosol from the container is sprayed into the outer space and which is mounted on the valve stem and has a channel connecting the valve stem to the outer space, an aerosol a cap formed by a base mounted on a support located on top of said container and a lid that rises from the base to cover the trigger mechanism on both sides thereof, the trigger mechanism having a stem mounting socket, mounted on the valve stem, a spray head located on the outer end of the trigger channel, the trigger in close proximity to the spray head and the curved portion connecting the back wall of the cap and the trigger according to the invention optionally includes restrictive means for holding the valve stem in the stem seat, located between the rear wall of the cover and the curved part at the rear of the trigger and made in the form of an insert or protrusion on the rear wall of the cover.

 In this case, preferably the aerosol contains an amount of propellant at least two times the amount of the solution comprising at least a component for controlling harmful insects, and the spraying intensity of the aerosol is at least 5 g in 5 seconds.

 In addition, preferably the aerosol contains an amount of propellant in excess of 2-7 times the amount of a solution comprising at least a component for controlling harmful insects.

 Preferably, the aerosol contains an amount of propellant in excess of 3-5 times the amount of solution comprising at least a component for controlling harmful insects and a solvent, wherein the amount of solvent to be sprayed is at least 4 ml per 20 sec.

 The term “pest control efficacy” in the present invention means all exposures to pests to control them, such as insecticidal effects, rapid immobilization, insect repellent, and the like.

 By using this aerosol spraying device, such a spraying is created that the concentration of the component for controlling harmful insects in the air in the space where the spraying took place does not decrease for at least 5 minutes after spraying, and the concentration of the component for controlling harmful insects in air can be maintained for a long period of time at a higher level than using conventional aerosol, whereby they achieve excellent effectiveness in the fight against harmful sekomymi. Despite the fact that a conventional intensive type aerosol spray device, on the contrary, gives a high concentration of the component immediately after spraying, this concentration rapidly decreases after spraying. As a result, the effectiveness of the control of harmful insects decreases and becomes insufficient.

 This is explained in more detail using an example.

 After the aerosol has been sprayed from the aerosol spray device, the concentration of the insect control component released into the air in the treated space is determined by the absolute amount of the component released from the aerosol spray device. However, if the liquid droplets formed by spraying with this device are very small, they disperse immediately after spraying and do not reach the harmful insects that must be combated, or the component evaporates quickly from aerosol and the concentration in the air reaches its maximum values immediately after spraying and then gradually decrease due to diffusion. Conversely, if the liquid droplets are too large, then they fall out of the treated space before the component is sprayed, so that the concentration in the treated space does not rise high enough, and soon begins to fall. And if the size of the liquid droplets are within certain limits, then they can exist in space for quite a long time. During this time, the component is released from the droplets, the concentration in the air continues to increase and begins to fall only after a certain period of time. Thus, if the concentration in the air continues to increase over a sufficiently long period of time, then the effective concentration of the component for combating harmful insects in the air in the treated space will remain long enough and will have an effective effect on these harmful insects. One of the objectives of the present invention is to create such spray conditions.

 However, it should be noted that the concentration in the air depends not only on the particle size of the liquid, but it is also affected by the rate of release and evaporation rate of the component to control harmful insects from liquid droplets, as well as the rate of diffusion from the treated space and other factors.

 The object of the present invention is solved by means of an aerosol spray device based on a new concept, according to which, in a sprayed liquid, which is a stream of liquid droplets, spraying from an aerosol spray device, the concentration of the component for controlling harmful insects in the air does not fall during 5 minutes after spraying from the device.

 The use of a conventional intensive aerosol spray device is often accompanied by wetting of the treated surfaces or an increase in the length of the torch. On the contrary, the use of the aerosol spraying device of the present invention, which makes it possible to obtain a sprayed liquid in which the concentration of the insect control component does not decrease for at least 5 minutes from spraying, can successfully avoid wetting of the treated surfaces and an increase in the length of the torch.

 The preferred aerosol spraying device is a device for producing a sprayed liquid in which the concentration of the insect control component in the treated space does not decrease for at least 5 minutes, preferably 7 minutes, after spraying.

 The expression "concentration (in air) in the treated space does not fall for at least 5 minutes" in the text of this application includes the situation when the concentration in air reaches its maximum and remains basically at this maximum level, and a situation where the concentration in the air increases for at least 5 minutes immediately after spraying. The latter situation is preferred.

 The term "treated space" in the text of this application means a space in the air surrounded by a trace of particles containing a component for controlling harmful insects and sprayed from an aerosol spray device.

 The term "after spraying" in the present text means "after the time when spraying from the aerosol spraying device was completed." The term "sprayed liquid" as used herein refers to a substance that has been sprayed from an aerosol spray device.

 Although the present invention does not limit the means by which the concentration of the insect control component is reduced in the treated space for at least 5 minutes after spraying from the aerosol spraying device, so long as this goal is achieved, it is no less preferable that the spray intensity is 5 g or more in 5 seconds, and at the same time that the volume ratio of propellant to the main solution in the aerosol is 2 or higher. Thus, the above concentration in air is created, and this prevents the wetting of the treated surface and the increase in the length of the torch, and at the same time provides an effective effect on harmful insects.

 With the indicated ratio of the propellant to the main solution and the specified spraying intensity, the sprayed particles containing the pest control component must be of suitable size to reach more distant insects and, as a result of diffusion, occupy much larger volumes (the volume occupied by the sprayed particles in the result of diffusion, in this text will be called the "diffusion volume"), compared with conventional aerosol spray devices (for example, achieving 6 times greater diffusion th volume than when using a conventional aerosol spraying device through 2.4 seconds after spraying). Thus, an effective concentration in the air is maintained for a long time, a more effective effect on harmful insects is provided, and insects located at a greater distance are exposed to this effect.

 In order to achieve a more pronounced effect, it is preferable that in the aerosol spray device of the present invention, the volume ratio of propellant to the main solution is from 2 to 7, and the spray intensity is from 5 to 15 g / 5 seconds.

 In another preferred embodiment, the aerosol spray device of the present invention, the propellant is used in an amount 3-5 times the volume of the main solution, including a component for controlling harmful insects and a solvent, and the amount of solvent to be sprayed is not less than 4.0 ml / 10 seconds (this option will hereinafter be called the 5th embodiment of the invention).

 This embodiment of the aerosol spray device is preferably an intensive spray device.

 When using the 5th embodiment of the invention, in which the volume ratio of propellant to the main solution is within certain limits, and the amount of solvent contained in the main solution to be sprayed is not less than 4.0 ml / 10 seconds, the aerosol spray device It has a desired effect, preventing harmful insects from moving from areas subjected to spraying, and gives an excellent insecticidal effect. More specifically, when used against harmful insects, especially fast-moving ones such as cockroaches, the 5th embodiment of the aerosol spraying device of the present invention limits their activity, allowing them to move a little, and effectively kills these insects.

 When using a conventional aerosol spray device, a harmful insect, even after it has been sprayed, sometimes retains the ability to move. In this case, the operator is likely to continue spraying until the insect stops moving. On the other hand, since the 5th embodiment of the aerosol spraying device of the present invention can suppress the movement of harmful insects from the areas subjected to spraying, it is possible to shorten the spraying time, i.e., the aerosol consumption is reduced. Due to the effective immobilization of harmful insects, the amount of aerosol dispersed in the environment can be controlled to minimize environmental pollution.

 Exposure to immobilize harmful insects (an effect that reduces the distance they can travel) after spraying is different from a purely insecticidal effect. In other words, if an excellent insecticidal effect is achieved, then this is not necessarily accompanied by an effective reduction in the distance that harmful insects can travel after spraying.

 In the 5th embodiment of the present invention, the amount of solvent to be sprayed is preferably 5.0 ml / 10 seconds or more, even better 6.0 ml / 10 seconds or more. As long as the above effects are provided, the upper limit of the amount of solvent to be sprayed is not limited, but it is preferable to be about 10.0 ml / 10 seconds.

 The 5th embodiment of the aerosol spray device according to the invention is preferably an intensive atomization device; the 5th embodiment gives more reliable effects when it is an intensive atomization device. The term "intensive spraying device" in this text refers to a device that allows you to get per unit time the volume of atomized liquid, 3-7 times greater than when using a conventional device. More specifically, the spray intensity (i.e., the amount of aerosol sprayed per unit time) should preferably be from 20 to 100 ml / 10 seconds, even better from 25 to 70 ml / 10 sec.

 In the present invention, the spray rate and the amount of solvent to be sprayed are expressed as the amount sprayed in 5 or 10 seconds. These amounts were determined by changing the amount of aerosol or the amount of solvent that was released over a period of 5 seconds or 10 seconds. Measuring the amount sprayed over a period of time shorter than 5 seconds does not give accurate results for an aerosol spray device. Accordingly, the amount sprayed in 5 seconds or 10 seconds was taken as a standard.

 Means for providing such intensive spraying include selecting a valve or poppet diameter to provide the desired spraying, as well as adjusting the spraying pressure. Any means capable of providing the above intense spraying may be selected.

 The effect of the volume propellant on the base solution, the amount of sprayed solution and the type of spraying device (i.e. intensive spraying or not) on the above-described efficiency of the 5th embodiment of the device according to the invention are shown below with reference to specific examples.

 (A) Intensive type aerosol spray device containing an aerosol consisting of 50 ml of a basic solution containing 0.5 g of a component for controlling harmful insects (solvent to a total volume of 50 ml) and 250 ml of propellant (main solution: gas propellant = 1: 5.00 by volume).

 (B) An intensive type aerosol spray device containing an aerosol consisting of 70 ml of a basic solution containing 0.5 g of a component for controlling harmful insects (solvent to a total volume of 70 ml) and 230 ml of a propellant (main solution: gas propellant = 1: 3.33 by volume).

 After comparing the aerosol spray devices (A) and (B), it turned out that the device (B) is superior to (A) in the above-described efficiency, regardless of the fact that both devices provide the same spray intensity (both devices are intensive spray devices, providing approximately 3-fold superior in spraying intensity compared to conventional type devices) and have the same component content for controlling harmful insects in an aerosol. Those. the use of an increased amount of solvent in the main solution, which leads to an increase in the ratio of the main solution to the propellant gas, as well as to an increase in the amount of solvent sprayed, enhances the above effects.

 In cases where the spraying intensity of the device (A) is further increased, for example, by about 5 times to obtain the device (B), the device (B) has a stronger effect due to the increased spraying intensity compared to the device (A). In the 5th embodiment, a higher spray rate is preferred.

 If the 5th embodiment of the aerosol spray device of the present invention is compared with a device of a different type, with the same content of the active ingredient (component for controlling harmful insects), it can be seen that although the concentration of the active ingredient in the air after spraying is almost equal, the device according to This option gives a noticeable reduction in the distance of movement of harmful insects and at the same time has an excellent insecticidal effect.

 These effects will be explained more specifically.

 The liquid was sprayed using an aerosol spray device according to the 5th embodiment of the present invention (sample (2) according to Example 5) and using an aerosol spray device other than the device according to the 5th embodiment (sample (3) according to Example 5), and measured the concentration of the component for combating harmful insects (imiprotrin) in the treated space.

Method of measurement:
A sampling tube containing approximately 3 g of silica gel was placed inside a closed chamber. Sprayed liquid in the direction of intersection of the wall and floor for a given period of time. For each device, the time was adjusted so that the amount of spray component for controlling harmful insects was the same.

 Air in the chamber was sucked through a sampling tube for 3 minutes at a speed of 15 λ min and the particles sprayed in the air were trapped in silica gel. Sampling began immediately after spraying and was repeated at predetermined time intervals for 20 minutes after spraying. The insect control component trapped in silica gel was analyzed using gas chromatography to determine the concentration of this component per cubic meter. m

 The concentration of the insect control component in the air (μg / cubic meter) = value of the component obtained as a result of analysis 4 (μg) / [sampling rate (λ min) x sampling time (min) x 1000].

 The results showed that the 5th embodiment of an aerosol spray device and another aerosol spray device gave almost the same concentration of the component for controlling harmful insects in the air.

 Despite the fact that the concentration of the component in the air was almost the same, the sample obtained using the 5th option allowed us to significantly reduce the distance that the insects moved after spraying, and gave an excellent insecticidal effect. Accordingly, the effects obtained with option 5 are obtained not only due to the action of the component for controlling harmful insects (thanks to the active ingredient), but also due to the combined action of the component for controlling insects, solvent, propellant, and the ratio of these components , spray intensity and amount of solvent sprayed.

 The aerosol spray device of the present invention relates not to those aerosol spray devices that spray all the contents at a time, but to the type of spray device that allows spraying repeatedly to control harmful insects.

 The aerosol spraying device of the present invention, of course, can be used in relation to the combination of an aerosol container containing a mixture of propellant and main solution that is closed inside, which characterizes the present invention, and an aerosol cap of one type or another, and is not limited to the combination of a container and an aerosol cap with a trigger, which is an embodiment of the present invention.

 The design of the aerosol spray device of the present invention is described below.

 In FIG. 2 shows a top view of the cap 2 of the aerosol spray device 10 shown in FIG. 1. In FIG. 3 shows a bottom view of the cap 2 of the aerosol spray device 10 shown in FIG. 1. In FIG. 4 is a side sectional view of the cap 2 of the aerosol spray device 10 shown in FIG. 1. In FIG. 5 shows a side view in section of the cap 2 in working condition with a disconnected seal 7.

 In FIG. 4, where a sectional side view is given, the trigger 3 is held by a seal 7. Even if a certain force is mistakenly applied to the trigger 34 during storage or transportation, the trigger 3 cannot press the valve stem 6 and release an aerosol. When the seal 7 is removed, the seat socket for the stem 35 and the valve stem 6 are connected to each other, as shown in FIG. 5. When the trigger 34 is pressed with a finger, the trigger 3 rotates counterclockwise around the locking lever 33, which is held in the support limiter 42 of the stiffener 41, whereby it presses on the valve stem 6.

 As can be seen from FIG. 3, the cap 2 used in the present invention has a gap 45 (at the lower end of the circumferential wall 43 in the housing) that is wide enough to allow the cap removal device 2 to be inserted through it. Therefore, the cap 2 can be easily removed by inserting fixtures through clearance 45.

 In FIG. 8 shows another example of an aerosol spray device of the present invention.

 The aerosol cap 111 of this example comprises a trigger 131 having a seat for the rod 139, a spray head 138, a channel 137 connecting the seat for the rod 139 and the spray head 138, as well as the trigger 134 and the housing 119. The base 118 of the aerosol cap 111 is supported to a support 5 located on top of the container 1. The housing 119 extends upward from the base 118, surrounding the trigger 131 on both sides. At the rear of the trigger 131 there is a curved portion 133 for connecting the rear wall 121 of the housing 119 and the trigger 131. When the trigger 134 of the trigger 131 is pulled, the valve stem 6 is pushed down by the seat for the stem 139 and the aerosol contained in the container 1 is sprayed from the spray head 138 through the channel 137. On the other hand, the seal 117 is connected to the edge of the side wall 120 of the housing 119 by means of an open element 116, beyond which the seal 117 can be torn off so that the aerosol spray device becomes and for use. To make it easier to tear off the seal 117, the tear-off element 116 can be made narrower and / or thinner, which prevents the landing seat for the stem 139 from getting on the stem due to the difficulty of tearing the tear-off element 116, as well as prevent inadvertent spraying.

 A feature of the example is that the limiting means 140 for retaining the fixation of the seating seat for the stem 139 on the valve stem 6 is inserted into the lumen of the curved portion 133. In this particular example, the protruding wedge-shaped element is used. Even if the operator lifts the trigger 131 by mistake when tearing off the seal 117 with a finger, the restrictive means 140 inserted into the lumen of the curved portion 133 restricts the movement of the trigger 131, minimizing the inclination of the seat for the stem 139, thereby preventing the mismatch of the seat for the stem 139 and valve stem 6. Although a protruding wedge-shaped element is used as the restriction means 140 in this embodiment, other restrictive means may be used. For example, an element cast along with the back wall 121 and falling into the lumen of the curved part 133 can serve as a restrictive means, or it can be an insert inserted and fixed in the lumen of the curved part 133 until the lumen is filled. There may be a locking mechanism between the protruding element or insert and the rear wall 121 so that the protruding element or insert cannot fall through the lumen of the bent portion 133.

 On the other hand, the aerosol (contents) closed in the aerosol container 1 of the aerosol spray device of the present invention mainly consists of a stock solution containing at least a component for controlling harmful insects and a propellant. If desired, the aerosol may contain surfactants, corrosion inhibitors, action enhancers, flavors, deodorants, fixatives, and the like.

 The harmful insect control component used as the active ingredient of the present invention includes insecticidal, controlling and repelling agents for so-called harmful insects, such substances as insecticides, repellents, bloodsucking inhibitors can be used , insect growth regulators, anti-juvenile hormones, acaricides, anticides and borericides. They can be used either individually or in a mixture of two or more of these substances, in accordance with the purpose or need.

Among the insect control components useful in the present invention are pyrethroid compounds. Examples of pyrethroid compounds are phenotrin- (3-phenoxybenzyl d-cis / trans-chrysanthemate), perimetrin- (3-phenoxybenzyl d1-cis / trans-2,2-dimethyl-3- (2 ', 2'-dichlorovinyl) -cyclopropanecarboxylate ), resmetrin - ((5-benzyl-3-furyl) methyl-d-cis / trans-chrysanthemate), allethrin- (d1-3-allyl-2-methyl-4-oxo-2-cyclopentenyl d1-cis / trans - chrysanthemum), phthalthrin- (1,3,4,5,6,7, -hexahydro-dioxo-2-indolyl d1-cis / trans-chrysanthemate), empentrine (1-ethynyl-2-methyl-2-pentenyl d1 cis / trans-chrysanthemate), 1-ethynyl-2-ethyl-2-pentenyl-2,2,3,3-tetramethyl-cyclopropanecarboxylate, 1-ethynyl-2-methyl-2-pentenyl-2,2 -dimethyl-3- (2 ', 2'-dichlorovinyl) -cyclopropanecarboxylate, pralletrin

 Hormones or anti-hormones of harmful insects, such as juvenile hormones, such as methoprene, anti-juvenile hormones, such as precocene, and molting hormones, such as ecdysone, are also included in insect control components.

In addition to components for controlling harmful insects, various chemicals can be added to the aerosol. For example, insect or rodent repellent substances, bactericidal substances, antifungal agents, deodorants, flavors, colorants, and the like can be included. Examples of insect repellents or rodents
2,3,4,5-bis (delta-butylene) -tetrahydrofurfural,

Deodorants include lauryl methacrylate. Flavors include ginger oil, citronella oil, lemon oil, lemon sorghum oil, orange oil, eucalyptus oil and lavender oil.

 The pest control component is preferably used in an amount of 0.01 to 1.0% w / v (m / v) of the amount of solvent.

 From this component, a stock solution is prepared by dissolving in a common solvent. Any solvent used in cosmetics and aerosol preparations without restrictions may be used. For example, water and organic solvents may be used.

 Any organic solvent commonly used in aerosol formulations may be used without any limitation. Examples of suitable organic solvents include aliphatic hydrocarbons such as hexane, kerosene, n-pentane, isopentane and cyclopentane; aromatic hydrocarbons such as benzene, toluene and xylene; halogenated hydrocarbons such as dichloromethane and carbon tetrachloride; alcohols such as ethanol, isopropyl alcohol, ethylene glycol; ethers such as acetone, methyl ethyl ketone, diethyl ether; esters such as ethyl acetate and isopropyl myristate; nitriles such as acetonitrile; acid amides such as dimethylformamide; vegetable oils such as soybean oil, cottonseed oil. One or more solvents selected from these examples may be included in the aerosol to control harmful insects.

 Water that is used as a solvent includes not only purified or deionized water, which is used in ordinary cases, but also deoxidized water. Deoxidized water best serves to prevent corrosion of the aerosol container. When using purified water or deionized water, it is necessary that the aerosol container is resistant to corrosion, preferably this is achieved by adding an anti-corrosion component, such as sodium benzoate, sodium nitrite, sodium citrate and ammonium citrate, or a combination of buffering components to adjust the pH, such as primary sodium phosphate - secondary sodium phosphate, ammonium benzoate - sodium hydroxide, sodium benzoate - benzoic acid, ammonium benzoate - aqueous ammonium, ammonium benzoate - benzoic acid, secondary SFAT potassium - sodium hydroxide, sodium hydroxide - sodium hydrogen maleate, sodium carbonate and sodium tris-maleate hydroxide - sodium hydrogen carbonate. In cases where the inner wall of the aerosol container for controlling harmful insects is coated with synthetic resin, there is no need for anti-corrosion components.

 If water is used as a solvent, since many of the above-described components for controlling harmful insects are poorly soluble in water or insoluble in water, they are emulsified, dispersed or solubilized in water with a surface-active agent or a solvent compatible with water and organic solvent. Examples of surface active agents are one or more compounds selected from the following: monooleate, sorbitan monostearate, sorbitan monolaurate, sorbitan trioleate, polyoxyethylene ethylene monooleate, polyoxyethylene nonylphenyl ether, polyoxyethylene cured castor oil, tripolyoxyethylene alkylene 1,3-butylene glycol, decaglycerol monooleate, diglycerol monooleate, propylene glycol dioleate, polyoxyethylene stearamide, polyoxyethylene polyoxypropylene glycol, sorbitan sesquioxide, polyoxyethylene (2) lauryl ether, diglycerol monooleate and hexaglycerol polyiricinoleate, lauroyl glutamate octyl dodecyl ether, stearyl alcohol, lanolin fatty acid and polyvinylpyrrolidone. These compounds belong to the category of surface active agents. In general, a surface active agent is a mixture formed by compounds with different degrees of polymerization, similar to high molecular weight compounds. For convenience, such mixtures are named for the compound forming the largest part in the mixture. Accordingly, the dispersants listed above include not only the surface active agents sold under the names given, but also those compounds whose properties or specifications correspond to the commercial products listed below. For example, “sorbitan sesquioxide” includes any substance that exhibits substantially the same properties as NIKKOL SO-15R manufactured by Nikko Chemical Co., Ltd. In this case, this substance is used in an amount of from 0.1 to 5.0% (m / v), preferably from 0.5 to 2.0% (m / v).

 A solvent compatible with water and an organic solvent includes propylene glycol, propanol and butyldiglycol. Such a solvent is used in an amount of from 10 to 80% (m / v), preferably from 40 to 60% (m / v). If desired, this solvent can be used in combination with a solvent other than water, which solvent will facilitate emulsification or dispersion and which will also facilitate further solubilization.

 In the 5th embodiment of the present invention, an organic solvent is preferred as a solvent. Alcohols, aromatic hydrocarbons and aliphatic hydrocarbons are also preferred. Aliphatic hydrocarbons having from 10 to 16 carbon atoms are most preferred.

 The preferred content of the solvent in the aerosol, although it is not limited until they reach the above effects, is from 8 to 40% (v / v).

 Although the solvent content in the 5th embodiment of the invention is not limited, until then the ratio of the main solution to the propellant and the amount of solvent sprayed is within these ranges, it is preferable that the content in the aerosol is from 16 to 25% (v / v ), since at such a solvent content, the effects achieved by the present invention are most pronounced.

 If desired, the aerosol may contain flavors, such as lemon, orange, eucalyptus and lavender oil, and deodorants, such as lauryl methacrylate.

 Known propellants can be used within the scope of the present invention.

 Examples of propellants are liquefied petroleum gas (LPG), propane, n-butane, isobutane, n-pentane, isopentane, cyclopentane, chlorine-free freon, dimethyl ether (DME), nitrogen gas, and liquefied carbon dioxide gas. Chlorine-free freon includes HFC-125, HFC-134a, HFC-143a, HFC-152a, HFC-32.

 These propellants can be used either individually or as a mixture of two or more gases. They are used in an amount of two or more times, preferably from 2 to 7 times, exceeding the volume of the basic solution.

 In the 5th embodiment, the propellant is preferably used in an amount of 3 to 5 times the volume of the stock solution.

 Fixatives include kerosene, 1,1,1-trichloroethane, methylene chloride, trichlorormonofluoromethane, carbon tetrachloride, 1,1,2-trichloro-1,2,2-trifluoroethane, chloroform, ethylene chloride and 1,2-dibromo-1,1,2 , 2- tetrafluoroethane.

 Examples of aerosol compositions (300 ml) closed in an aerosol container are shown in Table 1 (see end of description), however, the present invention is not limited to these examples.

 The object of control in accordance with the present invention includes a wide range of harmful insects living in houses and on the street, including ticks. Harmful insects living in homes and on the street include unsanitary insects and domestic insects. Unsanitary insects are cockroaches (e.g. Blatella germanica, Periplaneta fuliginosa, Periplaneta americana), flies (e.g. Musca domestica, Eusimulium, Sarcophagidae), mosquitoes (e.g. Culex, Aedes), lice, fleas. Domestic insects are insects such as termites, ants, spiders, bees, caterpillars, millipedes, domestic centipedes, Anobiidae, Bethylidae, buckworms (Chironomidae), Psychodidae, bedbugs, cycads, gribbie, bed bugs, woodlice, papillas, moths and biting twitches. House ticks include ticks that grow in the house and those that penetrate externally, such as Pyroglyphidae (e.g. Dermatophagoidae farinae hughes, Dermatophagoides pteronyssinus), Acaridae (e.g. Tyrophagus putrescentiae, Aleuroglyphus ovatphus privly, Glyu. G. , Glycyphagus domesticus), Cheyletidae (e.g., Cheuletus Fortis, Chelacaropsis moorei baker), Tarsonemidae, Cryptostigmata, as well as zoobiotic ticks, such as Ornithonyssus bacoti, Ornithonyssus sylviarum, Dermanyssus gides.

 The aerosol spray device according to the 5th embodiment of the invention is most effective against those harmful insects that run fast, such as cockroaches.

 As long as the above characteristics of the present invention are satisfied, the aerosol spray device of the present invention is applicable to combinations of an aerosol containing aerosol container with various aerosol caps, and the invention is not limited to the combination of a container and an aerosol cap with a trigger, which is one embodiment of the present invention.

BEST MODE FOR CARRYING OUT THE INVENTION
The present invention will be further described in more detail by way of examples, but the scope of the invention is not limited to these examples.

Example
An aerosol having the composition No. 3 according to table 1 and closed in the container 1 of the device shown in FIG. 1, as well as an aerosol closed in a conventional aerosol spray device (a), the specifications of which are given in table 4 (see the end of the description), were sprayed and the concentrations of the active ingredient (phthalthrin) in air were compared using the following test. A typical aerosol spray device contained an aerosol consisting of 120 ml of a basic solution, 450 mg of phthalthrin and 60 mg of resmetrin in kerosene No. 1 and 180 ml of LPG / DME propellant; this device sprayed at an intensity of 2.3 g / 5 sec. The spray intensity produced by the aerosol spray device of the present invention was about 6 g / 5 sec.

 A sampling tube (diameter - 15 mm; length - 100 mm; containing about 6.0 g of silica gel) was installed approximately in the center of 1.8 cubic meters of chamber at a height of 1 m from the floor. Within 5 seconds, the chamber was sprayed into the atmosphere from a window, which opened at a height of about 1.6 m. Immediately after spraying, the air in the chamber was sucked out through a sampling tube for 3 minutes with an intensity of about 18 λ min to catch particles in the air silica gel at regular intervals. The sampling tube was within the treated space, as described above.

Sampling was carried out within 1 hour from spraying. The active ingredient trapped using a sampling tube was analyzed using gas chromatography. The concentration of phthalthrin in air (μg / cubic meter) was calculated using the equation:
Air concentration (μg / cubic meter) = 1000 x phthaltrin analysis index (μg) / [sampling rate (λ / min) x 3 (min)] / cubic meter.

 The results are shown in FIG. 12. As can be seen from FIG. 12, compared with the concentration of phthalthrin in air obtained by spraying using the conventional device (a), the concentration obtained using the device of the present invention is lower immediately after spraying, but continues to increase for up to 7 minutes from spraying, and after that maintained at a high level. This suggests that a high concentration in the air is maintained for a long period of time, which significantly increases the insecticidal effect. It is believed that the particles of the active ingredient sprayed from the aerosol atomizer of the present invention are of average size due to the increased proportion of propellant, which has a strong effect on the concentration of the active ingredient in the air, as well as on the insecticidal effect.

 The characteristics of the particles atomized from the device of the present invention were measured (composition No. 3). It has been found that atomized particles include particles no larger than 11 microns in a ratio of 32.3 ± 5.8%.

 The diffusion volume of the material sprayed from the aerosol spray device of the present invention (composition No. 3) and from the conventional device (a) was measured. Material was sprayed from each of these devices and the volume occupied by the sprayed liquid droplets was measured (i.e., the amount of space surrounded by the trail indicated by liquid droplets). The results are shown in FIG. thirteen.

 As shown in FIG. 13, the device of the present invention provides a spray of material such that the diffusion volume increases at a noticeably greater rate compared to conventional device (a). The diffusion volume of the material sprayed from the device according to the invention was approximately 6 times greater than the volume of material sprayed from the conventional device 2.4 seconds after spraying. From these results it can be seen that the insect control component is in the air at an effective concentration for a longer time and produces a significantly stronger insecticidal effect.

Example 2
The aerosol spray device for controlling harmful insects of the present invention was tested for effectiveness using the following method.

 The spray intensity with the device of the present invention was about 6 g / 5 seconds. For comparison, a conventional aerosol spray device (a) was used.

Method and results:
A stainless steel cage (250 mm x 250 mm x 250 mm) containing 20 house flies (musca domestica) (males / females = 1: 1) was suspended from the ceiling and sprayed horizontally to the cage from approximately 1 second m, 1.5 m and 2.0 m from the center of the cell. Counted the number of flies and mortality (%) after 24 hours. The test was performed twice, the results were averaged. The results are shown in table 2 (see the end of the description).

 As can be seen from table 2, the aerosol spray device of the present invention is superior to the conventional device (a) in terms of speed of effect and mortality rate. The action against harmful insects exerted by the device according to the invention extends to a greater distance; this is achieved due to the fact that the sprayed particles have optimal characteristics and therefore fly further.

Example 3
A comparison was made on the degree of wetting of the treated surface between a conventional aerosol spray device (a), a comparative aerosol spray device having the same specifications as (a), except for a higher spray intensity (6.0 g / 5 sec), and the aerosol spray device of FIG. 1 containing the aerosol indicated in table 3 (compositions N 1-4 according to table 1), in container 1 (device of the present invention). White paper was placed on a plane and treated with each aerosol from a distance of 20 cm for 2 seconds. The degree of wetting of the paper was compared by area (length L (cm) x width W (cm)). Next, measure the length of the torch. The results are shown in table 3 (see the end of the description).

 The efficacy of controlling flies using an aerosol spray device was compared according to Table 3. A stainless steel cage (250 mm x 250 mm x 250 mm) containing house flies (musca domestica) was suspended from the ceiling and sprayed for about 1.5 seconds horizontally to the cell from a distance of 75 cm from the center of the cell. Counted the number of flies and mortality (%) after 24 hours. The test was performed twice, the results were averaged. The results obtained are shown in table 3.

 As can be seen from table 3, despite the fact that the device of the present invention gives an increased spray intensity compared to conventional device (a), the degree of wetting of the wall surface as a result of spraying with the first device is almost equal to the degree of wetting with the second device, and when this does not increase the length of the torch. The device according to the invention also makes it possible to limit the increase in the length of the flare return from the flare source.

 It can be seen from the results in Table 3 that with the same amount of aerosol sprayed per unit time, all devices of the present invention exhibit a satisfactory insecticidal effect, while there is a tendency to some decrease in this insecticidal effect with a decrease in the proportion of the basic solution.

 All this suggests that the conventional device (a) gives satisfactory results in the field of moisture and torch length, but is seriously inferior in insecticidal action; the comparative device gives relatively satisfactory results in insecticidal action, but is seriously inferior in that it gives strong wetting of the surface; thus, these devices do not meet all the requirements for slight wetting of the surface, in terms of torch length and insecticidal action.

 On the other hand, the aerosol spraying device of the present invention is superior to all other devices in terms of mild surface wetting, torch length and insecticidal action. In particular, it can be seen that the insecticidal effect of the device of the present invention is further enhanced when the ratio of propellant to stock solution is in the range 200/100 (= 2) to 260/40 (= 6.5).

Example 4
Testing the effectiveness of the control of harmful insects using the aerosol spray device of the present invention.

 Approximately 100 house flies (musca domestica) (female / male = 1: 1) were released into the chamber with a volume of 1.8 cubic meters. After some time, spraying was performed for 1.7 seconds using each of the aerosol spray devices shown in Table 4 (see the end of the description) (the device of FIG. 1). The number of immobilized flies was calculated, mortality (%) was determined after 24 hours. The results obtained are given in table 4.

 As can be seen from table 4, the device of the present invention has excellent characteristics in terms of speed of exposure and mortality and has an excellent effect in the fight against harmful insects even in practice, compared with conventional devices a, b, c. The efficacy and effectiveness of the aerosol spray device of the present invention is fully demonstrated in practice.

 An intensive aerosol spray device was taken, the spray intensity was adjusted to 27 ml / 10 seconds, which corresponds to 6 ml of solvent / 10 seconds. The concentration of the insect control component continued to increase for 5 minutes or longer.

 Sample 2 — stock solution: propellant = 1: 3.44 (v / v).

 In the aerosol container of FIG. 1 was closed with 67.5 ml of the main solution (0.6 wt.% Solution of imiprotrin in kerosene N 1, which was used as a solvent) and 232.5 ml of the same propellant as for sample 1, receiving 300 ml of aerosol.

 An intensive aerosol spray device was taken, the spray intensity was adjusted to 45 ml / 10 seconds, which corresponds to 10 ml of solvent / 10 seconds. The concentration of the insect control component continued to increase for 5 minutes or longer.

 Sample 3 — stock solution: propellant = 1: 1.22 (v / v).

 In the aerosol container of FIG. 1 closed 135 ml of the main solution (1.5 wt.% Solution of imiprotrin in kerosene N 1, which was used as a solvent) and 165 ml of the same propellant as for sample 1, receiving 300 ml of aerosol.

 An intensive aerosol spray device was taken, the spray intensity was adjusted to 9 ml / 10 seconds, which corresponds to 4 ml of solvent / 10 seconds. The concentration of the insect control component continued to increase for 5 minutes or longer.

 Sample 4 — stock solution: propellant = 1: 5.67 (v / v).

 In the aerosol container of FIG. 1 closed 45 ml of the main solution (0.9 wt.% Solution of imiprotrin in kerosene N 1, which was used as a solvent) and 255 ml of the same propellant as for sample 1, receiving 300 ml of aerosol.

 An intensive aerosol spray device was taken, the spray intensity was adjusted to 27 ml / 10 seconds, which corresponds to 4 ml of solvent / 10 seconds. The concentration of the insect control component continued to increase for 5 minutes or longer.

(2) Insects for testing
Adult female cockroaches, Periplaneta fuliginosa and Blatella germanica were used as insects for testing.

(3) Test method
Simily paper, on which concentric circles with radii from 10 to 70 cm are applied, was placed on the floor of a chamber with a volume of 35 cubic meters. m. A cylinder (diameter - 20 cm; height - 45 cm) containing 10 cockroaches was placed in the center of concentric circles, and a coating with a hole of 5 cm in diameter in the center was placed on top of the cylinder. Spraying was performed through the hole for 6 seconds and immediately after that the cylinder was removed. The state of the insects was examined and the distance that each insect crawled from the center of the concentric circles was measured (see Fig. 14).

The values of MD ₅₀ (distance from the center to the position where 50% of the insects were immobilized) and MD ₉₅ (distance from the center to the position where 95% of the insects were immobilized) were obtained.

 Then immobilized insects were moved to a separate container and continued to observe, resulting in a mortality rate (%) after 24 hours.

 The above tests were performed twice, the results were averaged.

 The test method is illustrated in FIG. 14, the results are shown in table 5 (see the end of the description).

 Test time 6 seconds.

 (4) Test results.

 From the effect on Peripianeta fuliginosa (table 5) it can be seen that samples 1 and 2 obtained using devices according to the 5th embodiment of the invention made it possible to obtain significantly shorter insect travel distances than on samples 3 and 4, and at the same time gave a sufficient insecticidal effect .

 Sample 4 is an intensive aerosol spraying device, in which the amount of solvent sprayed is within the range of the 5th embodiment, but the ratio of the main solution to the propellant is outside the range of the 5th embodiment. Thanks to this, cockroaches moved a greater distance.

 When the test described above was carried out on Blatella germanica, the results were almost identical. That is, samples 1 and 2, corresponding to the 5th embodiment of the invention, gave significantly shorter distances for the movement of insects and a sufficient insecticidal effect.

Example 6
Immobility test.

This test was carried out on samples 1, 2, 3 and 4 of example 5 with the aim of measuring KT ₅₀ (time (in seconds) for which 50% of the insects were immobilized), KT ₉₀ (time (in seconds) for which 95% of insects were immobilized) and mortality after 24 hours.

 The test method is illustrated in FIG. 15. Ten cockroaches (Periplaneta fuliginosa) (test insects 12) were placed in a cup 11 (diameter 10 cm, depth 10 cm). A cup 11 containing insects was mounted diagonally to the floor. Using each sample (test device 13), spraying was performed for 1 second from a distance of 50 cm from cup 11 and approximately 40 cm from the floor.

 Immediately after spraying, the cockroaches were transferred to a container for observation (diameter - 50 cm, height 12 cm) and the number of immobilized insects was recorded. Then the insects were transferred to a clean container, where there was food and water. After 24 hours, dead insects were recorded.

 The results obtained are shown in table 6 (see the end of the description).

From table 6 it is seen that samples 1 and 2 according to the 5th embodiment of the present invention are noticeably superior to samples 3 and 4 according to KT ₅₀ and KT ₉₀ . Comparing samples 1 and 2, both of which correspond to the 5th embodiment of the present invention, it can be seen that sample 2 spraying a larger amount of solvent is superior to sample 1.

 Industrial applicability.

 As described above, the aerosol spray device of the present invention has an enlarged hole at the lower end of the circumferential wall in the cap. Due to the fact that a tool can be inserted into this hole, the cap is easily removable. In the present invention, erroneous tearing of the seal is prevented by inserting restrictive means into the lumen of the curved part and / or by making the tear-off element smaller and / or thinner in order to limit the lift of the trigger mechanism, maintain the position on the rod of the seat socket and prevent the seat socket from mismatching and valve stem.

 The aerosol spray device of the present invention is highly effective in controlling harmful insects. Being an intensive atomization device, this device nevertheless avoids excessive wetting of the surface and an increase in the length of the torch. Compared with a conventional aerosol spray device, the device according to the invention allows to obtain a spray in which liquid droplets have optimal particle characteristics, a large diffusion volume and the concentration of the active ingredient in the air stably remains for a long period of time, thereby ensuring high efficiency in controlling harmful insects ( i.e. insecticidal effect, immobilizing effect on insects, etc.).
